Purity: ≥98%
ZT-12-037-01 is a novel, potent, ATP-competitive and specific STK19-targeted inhibitor with IC50s of 23.96 nM and 27.94 nM for STK19 (WT) and STK19 (D89N), respectively. In vitro and in vivo, it is able to efficiently inhibit melanoma growth and oncogenic NRAS-driven melanocyte malignant transformation. It blocks the oncogenic NRAS-driven malignant transformation of melanocytes and interacts with STK19 protein with high affinity. An ATP-competitive inhibitor with an IC50 of 24 nM, ZT-12-037-01 prevents the phosphorylation of NRAS, the main isoform of the Ras family. Of all melanoma cases, 20% to 30% have activating mutations in NRAS. However, unlike BRAF, no anti-NRAS therapy has proven to be effective in decades of research.

ZT-12-037-01 treatment effectively inhibits NRAS phosphorylation in a time- and dose-dependent manner. Moreover, ZT-12-037-01'sIC50against STK19 increased in response to rising ATP concentrations, suggesting that ZT-12-037-01 is an ATP-competitive inhibitor of STK19. Mutant NRAS-STK19-driven melanocyte colony formation, proliferation, and tumor formation are all markedly inhibited by ZT-12-037-01 treatment. ZT-12-037-01'spro-apoptoticeffect is markedly amplified in cells that express oncogenic NRAS [1].
|
| ln Vivo |
ZT-12-037-01 is a very effective STK19 inhibitor with low in vivo toxicity. Additionally, it treats SK-MEL-2 xenograft melanoma in a dose-dependent manner (with NRASQ61R)[1].

| Solubility (In Vivo) |
Solubility in Formulation 1: 5 mg/mL (12.97 mM) in 50% PEG300 +50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
